if f(x) = 2x^ 2 + 3x,then what is f(−9)?
Answer:
f(-9) = 135
Step-by-step explanation:
Replace x with -9, and evaluate the expression.
f(x) = 2x² + 3x
f(-9) = 2(-9)² + 3(-9)
f(-9) = 2(81) - 27
f(-9) = 162 - 27
f(-9) = 135

Answer: As a fraction it is 145/2 and as a mixed number it is 72 1/2
Step-by-step explanation:
First write down the number like this, 72.5/1
Then multiply each number by ten like this, 72.5 x 10 = 725
And 1 x 10 = 10 and write that as a fraction like this, 725/10
Next do 725 divided by 5 = 145 and 10 divided by 5 = 2
And put that in a fraction like this 145/2
That is the fraction of 72.5%
As a mixed number you put the 72 as a whole number and 1/2 because 5 represents a half

Answer:
sqrt( 74)
8.602
Step-by-step explanation:
To find the distance between the two points we use the formula
d = sqrt( ( x2-x1)^2 +(y2-y1)^2)
= sqrt( ( 3- -2)^2 + ( -2 -5)^2)
= sqrt( (3+2)^2 + ( -7)^2)
= sqrt( 5^2 (-7)^2)
= sqrt( 25+49)
= sqrt( 74)
approximately 8.602325267

Tisha scored an average of 18 points in each of her first five basktetball
games. Altogether, how many points did she score in her first five
games?
Answer:
90 pts.
Step-by-step explanation:
In general, you need to multiply the average points she got in each game by how many games she played.
So therefore you'd do:
18 x 5
= 90 pts.
mr.wilson drives 450 miles in 7 hours. at this rate about how many miles does he drive in 6 hours????
A.) 101
B.) 254
C.) 340
D.) 386
Answer:
D
Step-by-step explanation:
Divide distance he drives by 7 to find hourly rate, then multiply this by 6
450 miles ÷ 7 ≈ 64.29
Then
6 × 64.29 = 385.74 ≈ 386 miles
Activity
In this activity, you will use a table of coordinate points to determine whether a function is linear or nonlinear. Billy hit a baseball to the bottom of

The value of x represents the horizontal distance traveled by the baseball, and the value of y represents the height of the ball from the ground.
-Part A
To determine whether a function is linear or nonlinear, check whether the rate of change is constant for every pair of coordinates. What is the rate
change in y, for the first two pairs of coordinates?
of change, change in
Answer: The rate of change in the y coordinate is 75. 78 - 3= 75.
Answer:
Part a: Answer is 1/2
78 - 3/150 - 0 = 75/150
= 1/2
Part b: Answer is -1/2
3 - 78/300 - 150
= -75/150
= -1/2
Part c: No, the two rates aren’t the same, because one is positive and the other is negative.
Part d: The rate of change of the function determined by using the two pairs of coordinates is not the same. So, the function modeling the movement of the ball is a nonlinear function

Step-by-step explanation:
a joker cap is in the form of a right circular cone of base radius 10.5cm and height 36cm. find the area of sheet to make 20 such caps....?
plz answer this
We know that
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.5
l = √(1406.5)
l = 37.5 cm
Now,
CSA of cone = πrl
=> 22/7 × 10.5 × 37.5
=> 22 × 1.5 × 37.5
=> 1237.5 cm²
Area of 20 caps = 20 × 1237.5
=> 24750 cm²
Answer:
24740 cm²
Step-by-step explanation:
First let us find the slant height (l) of the corn
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.25
l = √1406.25
l = 37.5 cm
Now let us use this formula to find the area of a corn
π r l
π × 10.5 × 37.5
1237.00 cm²
And now let's find the area of 20 caps or corns
1237.00 × 20
24740 cm²

If f(x) = â’2 8, what is f(â’1. 8)? 4 6 10 12.
Answer:
f(x) = [x] - 2 + 8
[x] is the notation for 'greatest integer function'
f(-1.8) = [-1.8] - 2 + 8 = -2 -2 + 8 = 4
The answer is 4
Step-by-step explanation:
The value of the function f(x) = [x] - 2 + 8 when x = -1.8 is 12
Given the function f(x) =[x] - 2 + 8, we need to find f(-1.8)
To get the value of f(-1.8), we will simply substitute x = -1.8 into the function to have:
f(-1.8) = -1.8 - 2 + 8
f(-1.8) = -3.8 + 8
f(-1.8) = 11.8
Since x is in a square bracket, we will round the value up to the nearest whole number, hence;
f(-1.8) = 12
Therefore the value of the function f(x) = [x] - 2 + 8 when x = -1.8 is 12

estimate the area of the following irregular shapes
Answer and Explanation: We will find the area of the given shape:
To find the area, we will count the number of squares of the shaded area.
While calculating the area for a more accurate estimate, we count the square as “1” if the shaded region covers more than half of each square. By counting the squares, the area is approximately 50 square units.
